Request: Target floating, unpinned Python version releases

[aep-sunlife]

Description:

Please support targeting the latest stable Python release, so that we can use this in CI/CD.

Justification:

I like to setup GitHub Actions CI/CD jobs that test my projects against the latest emerging programming language versions. That way, I get notified early of any breaking compatibility changes that may occur with each upcoming major version.

Are you willing to submit a PR?

No.

As a workaround, one could manually install Python from git HEAD, though this defeats the purpose of a Python provisioning workflow.
